The flowmeter (5) has at least one flow tube (130, S 130'), at least one pickoff sensor (170L, 170R) attached to the flow tube (130, 130'), at least one driver (180L, 180R) attached to the I L — flow tube (130, 130'), and meter electronics (20) in communication with the at least one pickoff sensor (170L, 170R) and driver Il C (180L, 180R). The method includes the steps of vibrating at least one flow tube (130, 130') in a drive mode vibration with the at N least one driver (180L, 180R), and receiving a sensor signal based on a vibrational response to the drive mode vibration from the at en. ) least one pickoff sensor (170L, 170R). At least one flow variable is calculated. A pickoff sensor voltage is measured, and it is de- termined whether the pickoff sensor voltage is below a predetermined voltage threshold (304). The at least one flow variable is cor- rected during periods wherein the pickoff sensor voltage is below the predetermined voltage threshold (304).
